|Aug-14-09|| ||eaglewing: <Zzyw>: Yes! 33. Ra8 Qb5+ 34. Kg1 Qc6! is clearly winning compared to Qe2. (35. Qa5 Qxa8! or Rd8 Qxc3 Rxd1 a1Q)|
|Aug-14-09|| ||David2009: Saturday's puzzle Tseshkovsky vs E Vladimirov, 1986 Black to play 28? Difficult
No prizes for spotting the theme of the puzzle - back rank mate - but there are a few difficulties. White
would like to escape with the loot by Qb8+ followed by Re2 and Qe5 so Black has to be careful.
I cannot find a win. I have found four false trails:|
(a) 28...Qb6 29 Qc3 Qc5 30 Qe3 and White breathes freely: 30... Qxe3+ 31 fxe3 Rxe1+ 32 Kf2=: Black wins the P at
(b) 28...Qb6 29 Qc3 Qe6 guards c8 and forks the Ne1/Ra2 30 Ra1! guards everything;
(c) 28...Qb6 29 Qc3 Qd4 30 Qe3! (or even 30 Qc8+ Kh7 31 Re2 Qd2 32 Qe8);
(d) 28...Qb6 29 Qc3 Qb3 30 Qc8+ Kh7 31 Qf5+ = perpetual check.
My best shot: 28...Qb6 29 Qc3 Qb1 30 Re2 a3 31 Kf1 a2 32 Rxa2 Qxa2 33 Qc8 draws by perpetual check.
I have spent over half an hour on this, domestic duties call, time to admit defeat; shake hands on metaphorical the draw and look up the
25...Qb7 wins. Now why didn't I pursue that further earlier?
|Aug-14-09|| ||Jimfromprovidence: Using the line first reported by <Random Visitor>, there’s an interesting, lengthy continuation that happens if white instead tries to get an escape square for his king as well as get his rook over to a8.
(Analysis courtesy of Rybka freeware.)
After 28…Qb7 29 Qc3 Qb1 30 Re2 a3, now 31 h3?! a2 32 Re8+ Kh7 33 Ra8 is the line for the above-described strategy.

After 33…Rxe1+ 34 Kh2 black is only up a pawn.

Black continues the hunt and gains success with precise play. 34 Rh1+ 35 Kg3 Qg6+ 36 Kf3 Qf5+ 37 Ke3 Qe6+ 38 Kd2 Qe1+ 39 Kd3 Qxf2! 40 Qc2 Qxc2+ 41 Kxc2 a1Q 42 Rxa1 Rxa1 does the trick.

Can you help me find 5.d3 in the opening explorer? After 1. e4 e5 2. Nf3 Nf6 3. Nxe5 d6 4. Nc4 Nxe4 then 5.d4 and white is a move ahead, no chance to catch back it seems to this game?, as the OE will sometimes do.

Can you help me find 5.d3 in the opening explorer?
Interestingly, it's not there: Opening Explorer
You might want to report it to cg.com to find out why not.
|Aug-14-09|| ||eaglewing: <Jimfromprovidence>: Maybe it is too late, but despite having looked at another Ra8-line, I don't get it. Why, in your line with 31. h3 and 33. Ra8 Rxe1+ 34. Kh2 I cannot simply go on with 34. ... a1Q, so not only being up a pawn?|
|Aug-14-09|| ||Deji: I Love this puzzle. Quite daunting if you don't know what to look out for - so many possible moves. Now, let's look at it.|
1) white knight is caught in an absolute pin
2) We can see a back rank mate assuming the rook had a direct check on the king.
3) What else do we have...? Black pawn wants to queen
4) White rook is hanging.
Let's see. If we could play RxN+, it would be mate. But the knight is protected by the queen...only by the queen. Try distracting the queen from protecting the knight and we have our answer. Qb7. White queen can only protect the knight alone the a5-e1 diagonal. So, Qa5. Next, Qd5 forks queen and rook. White queen cannot take because of RxN#. So, the hanging rook falls, and black threatens to queen the pawn on a1. It's a pity the white queen cannot even check the black king just once!
|Aug-14-09|| ||OBIT: On the 28...Qc5 try, one possibility is 29. Qb8+ (29. Qe4 has also been mentioned here as fully playable, but I'm thinking this check is even better) Kh7 30. Re2 (Better than 30. Qe8, as it gets the rook out of danger and keeps the queen active). In this position, Black has four moves that look reasonable: 30...Qc3, 30...Qa5, 30...Qc1, and 30...a3, and White plays 31. Kf1 against any of them. This breaks the threat of the back rank mate and keeps the a-pawn contained, i.e. 30...Qc3 31. Kf1 a3 32. Qa8 or 30...Qa5 31. Kf1 a3 32. Qb3 or 30...Qc1 31. Kf1 a3 32. Qb3 or finally 30...a3 31. Kf1 a2? 32. Rxa2 ("Thank you!") And, once the mate has been negated and the a-pawn contained, White can actually think about winning this game - can't White untangle his position by f3 and Kf2, then go for the W?|
As for why 28...Qc5 doesn't work, I'd say the problem is the free move White gets with the queen check. This gives Black one extra move to get his defense in order, and in this position that extra move is critical.
|Aug-14-09|| ||WhiteRook48: had the right idea but the wrong move|
|Aug-14-09|| ||sfm: One must love 25.-,Bxa2!!|
|Aug-14-09|| ||Jimfromprovidence: <eaglewing> <Maybe it is too late, but despite having looked at another Ra8-line, I don't get it. Why, in your line with 31. h3 and 33. Ra8 Rxe1+ 34. Kh2 I cannot simply go on with 34. ... a1Q, so not only being up a pawn?> |
Yes, I did not see the forest for the trees. Your line is clean, simple and wins a rook outright.
The Rybka line I put forward that continues with 34... Rh1+ wins a couple of extra pawns or so eventually, but it does take several more moves to earn that additional material.
So in this case a better "pure" line probably unnecessarily muddies things.
|Aug-14-09|| ||patzer2: <AugustAle> Thanks for the correction! I got the move right on my game collection, but was so focused on the actual combination beginning with 25...Bxa2!! that I also used it in my earlier post on the puzzle solution 28...Qb7!|

|Aug-14-09|| ||CHESSTTCAMPS: Black is down a knight for a passed a-pawn, but has white in a bind: the N is pinned on the 1st rank and there is a back-rank mate problem. With the Ra2 not helping to defend the N, the obvious tactical theme is to deflect the WQ. But which way? Several possibilities can be quickly eliminated: 28... Qb6 (my first thought on seeing the position) and Qc4 can be parried by Qe4. Qd4 is met by 29.Qb8+ followed by Qe8. This suggests:|
The perfect geometrical move, a queen opposition! It attacks the WQ, and takes b8, e4, and e7 away from the WQ. If now:
A) 29.Qxb7 Rxe1#
B) 29.Qa5 Qd5! (continuing to play 4-square with the WQ) 30.Qb4/c3 Qxa2 wins
C) 29.Qc3 Qb3! (Qe4? 31.Kf1 Rxe1+ 32.Qxe1 Qc4+ 33.Qe2 Qc1+ is drawn) creates too many overloads for white to solve:
C.1) 30.Qxb3(/Qc2) Rxe1#
C.2) 30.Qa5/Qe3 Qxa2 wins handily
C.3) 30.Qc8+ Kh7 31.Re2 (Qf5+? g6) a3 32.Kf1 (Qa8 a2 wins the queen) a2 33.Rxa2 Qxa2 and there's no good way for white to stop a Q trade into a winning endgame for black e.g. 34.Qe8 Qe6 wins. Or 34.Qc3 Qd2 35.Qe5 Qe3+ 36.Kg1 f5 and there's no defense to 37...Qe4, e.g. 37.f3 Qd4+
Time to check....
|Aug-14-09|| ||CHESSTTCAMPS: Oops - it seems I found a losing line that others found. I also looked at 29... Qb1 and didn't work it through.|
Nice puzzle - too bad the best defense was not played in the game.

|Aug-15-09|| ||patzer2: <Once> I understand. However, I think many wives, faithful husbands and Christian Bible believers would not find the joke amusing.|
|Aug-15-09|| ||doubledrooks: Black wins the exchange with 28...Qb7 29. Qc3 (if 29. Qa5 then Qd5!, a move it took me a while to see) Qb1 30. Re2 a3 31. Kf1 a2 32. Rxa2 Qxa2.|
